Dear all, I am trying to remotely debug the kernel using kgdb patch and the gdbmod available at http://kgdb.linsyssoft.com/getting.htm. Below are the steps... 1. I compiled the kernel source tree after applying the kgdb patch in TEST machine, 2. Transferred the whole kernelsourcetree from /usr/src/ of TEST machine along with object files to my Development machine 3. Transferred the modules from /lib/modules/2.6.8, modules from TEST machine to my Development machine's /lib/modules directory. On rebooting, the TEST machine in the newly compilled kernel, i get Waiting for gdb connection.. as i have modified the grub to pass the required kernel parameters. Now when i do this...............frm development machine... /*************************************************************************/ [root@vishalsoni linux-2.6.8]# gdbmod-2.2 vmlinux GNU gdb 6.0 Copyright 2003 Free Software Foundation, Inc.

SCSI subsystem initialized [New Thread 191] Error while mapping shared library sections: sd_mod.ko: Success. Error while reading shared library symbols: and so on............................... Its not able to locate the modules............. and the Symbol Tables and i need to put break points in these modules.. i need to back trace the functions........to know their names.......... Wud u plz suggest me , how i can achieve this....... and ne gud pointers, which tells how to remotely debug the kernel........... I am googling for the days and days.. Thanx in advance.
